[0002] In the field of processing non-drive axles for tractors, axle fixing and processing auxiliary equipment are key factors to ensure processing quality and efficiency.

[0003] At present, traditional axle processing fixtures mainly use simple mechanical structures to fix the axles, such as fixing the axles on the fixtures by bolts, nuts, etc. For auxiliary positioning during the axle processing, some equipment uses fixed support blocks and fixtures to perform preliminary positioning of the axle to ensure the basic position of the axle is stable during the processing.

[0004] In terms of adjustment functions, some existing fixing frames have limited height adjustment functions, usually by manually rotating the screw rod or using a hydraulic jack to achieve slight adjustments in the height of the axle.

[0059] Example 4

[0060] Specifically, the present embodiment also discloses a working method for a non-drive axle processing fixing frame for a tractor with multi-directional fine adjustment, comprising the following steps:

[0061] Step 1. Before starting work, the operator needs to conduct a comprehensive inspection of the entire fixed frame equipment. Check whether there are foreign objects stuck on the linear slide 1 4 and the linear slide 2 18 to ensure smooth sliding; check whether the connection lines of each motor such as the lifting motor 9, the drive motor 28, the vertical fine-tuning motor 29, the swing adjustment motor 40, the clamping control motor 47, the dual-axis motor, etc. are stable and whether there is any damage or looseness; check whether the working status of electrical components such as the electromagnet, the micro cylinder 45, the servo cylinder 20, etc. is normal, and input the corresponding parameters in the control system according to the specifications of the axle to be processed, such as length, diameter, height, etc.;

[0062] Step 2: The operator starts the drive motor 28, and the output shaft of the drive motor 28 drives the horizontal adjustment screw 27 to rotate. Since the external threads on the left and right sides of the surface of the horizontal adjustment screw 27 rotate in opposite directions, when the drive motor 28 rotates clockwise, the support components 26 on both sides of the surface of the horizontal adjustment screw 27 slide to the left and right sides respectively in the horizontal adjustment drive groove 24; when the drive motor 28 rotates counterclockwise, the support components 26 slide relatively. By accurately controlling the rotation direction and number of turns of the drive motor 28, several support components 26 are adjusted to appropriate positions to adapt to the length of the axle. At the same time, observe the sliding of the support component 26 in the support member slide groove 25 to ensure that it moves smoothly and without jamming. Use a crane or other lifting equipment to lift the axle smoothly to the fixed frame, and place the two ends of the axle on the top of the left and right axle support frames 41 respectively. During the placement process, pay attention to the horizontality and approximate center position of the axle, and try to place it in the center area of ​​the fixed frame to prepare for subsequent precise adjustment;

[0063] Step 3, start the clamping control motor 47, and its output shaft drives the clamping screws 43 in the two clamping control slides 42 to rotate through three sprockets 48 and chains. Since the external threads on both sides of the surface of the clamping screw 43 rotate in opposite directions, when the clamping screw 43 rotates clockwise, the two clamping frames 44 move relatively along the clamping screw 43. The operator controls the number of rotations of the clamping control motor 47 according to the approximate diameter of the two ends of the axle by observing or controlling the preset parameters in the system, so that the two clamping frames 44 quickly approach the two ends of the axle, but do not clamp them completely, and reserve a certain amount of fine-tuning space; according to the actual diameter specifications of the two ends of the axle, start the micro-electric cylinder 45, and the output shaft of the micro-electric cylinder 45 controls the clamping block 46 to lift upward, and gradually adjust the height of the clamping block 46 to make it fit closely with the surface of the axle. In this process, observe the force of the axle to avoid deformation of the axle due to excessive clamping force. At the same time, the clamping force is monitored in real time through the built-in pressure sensor to ensure that the clamping force is uniform and moderate;

[0064] Step 4: Turn on the vertical fine-tuning motor 29, and its output shaft drives the worm 30 to rotate. The worm 30 meshes with the surface of the worm wheel 32, so that the worm wheel 32 drives the vertical adjustment screw 33 to rotate. When the vertical adjustment screw 33 rotates clockwise, the vertical adjustment sleeve 34 moves upward in the vertical adjustment sliding groove 31, thereby driving the support lifting frame 37 to rise; when the vertical adjustment screw 33 rotates counterclockwise, the support lifting frame 37 descends. The operator controls the rotation direction of the vertical fine-tuning motor 29 according to the height requirements required for the axle processing. The height adjustment of the support lifting frame 37 is realized by adjusting the number of circles. During the lifting process of the support lifting frame 37, the limiting balls 36 around the surface of the vertical adjustment sleeve 34 slide in the ball slide grooves 35 around the inner wall of the vertical adjustment slide groove 31. At the same time, the four stabilizing slide bars 38 at the bottom of the support lifting frame 37 are slidably connected with the inner periphery of the support component 26. The stabilizing slide bars 38 and the limiting balls 36 work together to ensure the stability of the support lifting frame 37 during the lifting process, avoid shaking or tilting, and ensure the accuracy of the height adjustment of the axle.

[0065] Step 5: Start the swing adjustment motor 40, whose output shaft controls the swing adjustment component 39 to rotate on the top of the support lifting frame 37. The operator adjusts the angle between the axle support frame 41 and the support lifting frame 37 by controlling the rotation direction and angle of the swing adjustment motor 40 according to the angle requirements of the axle processing, thereby achieving fine adjustment of the angle of the axle. In order to ensure the accuracy of the angle adjustment, the angle sensor installed on the swing adjustment component 39 is used to feed back the rotation angle of the swing adjustment component 39 in real time. The operator can fine-tune the swing adjustment motor 40 according to the feedback information to achieve a precise processing angle of the axle.

[0066] Step 6: If it is necessary to adjust the height of the processing auxiliary unit 2, start the lifting motor 9, and the output shaft of the lifting motor 9 drives the driving gear block 8 to rotate clockwise, and the driving gear block 8 engages with the tooth surface of the lifting gear plate 7 to transmit, so that the auxiliary lifting frame 6 slides upward in the lifting slide groove 11. The operator controls the number of rotations of the lifting motor 9 according to the height of the axle and the processing requirements, and accurately adjusts the height of the auxiliary lifting frame 6. At the same time, observe the coordination between the limit slide bar 10 and the auxiliary lifting frame 6 to ensure that the auxiliary lifting frame 6 is stable and vertical during the lifting process. If the front and rear position of the processing auxiliary unit 2 on the top of the fixed unit 1 is to be adjusted, the auxiliary sliding frame 5 can slide back and forth on the linear slide rail 4. The operator controls the moving distance of the auxiliary sliding frame 5 on the linear slide rail 4 through the control system or manual operation, so that the processing auxiliary unit 2 reaches a suitable front and rear position to meet the processing requirements of different parts of the axle.

[0067] Step 7. During the axle processing, according to the approximate connection position of the accessories and the axle, the double-axis motor in the adjustment moving block 15 is started, and one end of the double-axis motor drives the adjustment gear 13 to rotate, and the adjustment gear 13 is meshed with the inner tooth groove on one side of the inner wall of the arc-shaped adjustment groove 12 to drive the adjustment moving block 15 to move along the arc-shaped adjustment groove 12, thereby realizing the rough adjustment of the position of the processing auxiliary frame 16. During the adjustment process, the rolling slider 14 rolls in the arc-shaped adjustment groove 12 to ensure that the adjustment moving block 15 moves smoothly, and the electromagnet on one side of the metal adsorption block 21 is energized to generate magnetic force to adsorb and fix the processing accessories of the axle. The operator adjusts the processing accessories according to the actual situation of the axle and the processing accessories. The connection position is further fine-tuned to make the position of the processing auxiliary frame 16 be precisely aligned with the axle by the metal adsorption block 21. If the position of the processing accessories needs to be adjusted more precisely, the displacement slider 19 can be driven to slide in the displacement inner groove 17 by the linear slide rail 2 18. The operator controls the extension and retraction of the servo electric cylinder 20 to move the displacement slider 19 on the linear slide rail 2 18. The industrial camera 22 takes real-time pictures of the position of the axle and the processing accessories, and feeds back the image information to the operator or the control system. The operator precisely adjusts the position of the displacement slider 19 based on the feedback information to improve the use flexibility and positioning accuracy of the workpiece adsorption component.

[0068] Step 8: During the axle processing, the position, clamping force, angle and other parameters of the axle are monitored in real time by using industrial cameras 22, pressure sensors, angle sensors and other equipment. The industrial camera 22 continuously captures the position changes of the axle and the processed parts. The pressure sensor feeds back the clamping force in real time. The angle sensor monitors the angle changes of the axle in real time. If the position, clamping force or angle of the axle is detected to be deviated, the control system automatically issues instructions to fine-tune the corresponding motors such as the vertical fine-tuning motor 29, the swing adjustment motor 40, the clamping control motor 47, etc., so that the axle is always kept in a precise processing position and state.

[0069] Step nine, after the axle processing is completed, first turn off the power supply of the electromagnet on one side of the metal adsorption block 21 to release the adsorption of the processed accessories, then start the micro-electric cylinder 45 to lower the clamping block 46, and then start the clamping control motor 47 to move the clamping frame 44 to both sides to release the clamping of the axle, and restore each adjustment component to its initial position, such as moving the support component 26 to the initial position through the driving motor 28, lowering the auxiliary lifting frame 6 to the lowest position through the lifting motor 9, and lowering the supporting lifting frame 37 to the initial height through the vertical fine-tuning motor 29, etc. At the same time, clean and maintain the equipment to prepare for the next processing.
